Describe and compare measurable attributes. 1. Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object. 2. Directly compare two objects with a measurable attribute in common, to see which object has “more of”/“less of” the attribute, and describe the differences.
Activies include using the pan balance scale and marked gram weights, the students will balance the witch's broomstick from the story " Room on the Broom"; weigh objects and compare density of the object; observe and predict weight of objects in a "sink or float" exercise.

Science and Engineering Practices
Planning and Carrying Out Investigations : Planning and carrying out investigations to answer questions or test solutions to problems to build on prior experiences and progresses to simple investigations, based on fair tests, which provide data to support explanations or design solution, (I-ESS 1-2)
Students will develop a tool to solve a simple problem.
Activities: Using the challange of Room on the Broom by Julia Donaldson, the students will design a wind proof witch's hat; repair the witch's broom without using tape, and design and construct a couldron stand.
Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object. (3-PS2-1)
Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.(3-PS2-2)
Activities: The students will experiment with potential vs kinetic energy by making marble runs and a swinging pendulum.
